Quizplus · Accepted Answer

All the options listed (A-D) are necessary for peak athletic performance. A good blood supply and system of blood delivery are essential for providing oxygen and nutrients to the working muscles. A well-developed respiratory system is required to take in enough oxygen and remove carbon dioxide efficiently. The coordination of the nervous system is crucial for sending signals to the muscles for movement and controlling balance and coordination. Finally, adequate supplies of nutrients, such as carbohydrates and proteins, are necessary for energy production and muscle repair and growth.
